El Grupo de Física Estadística de los sistemas Complejos les invita al siguiente seminario, que se realizará de manera presencial y online. Speaker: Miguel Gallego Ballester. University of Vienna. Title: Macroscopically nonlocal quantum correlations. Abstract: It is usually believed that coarse-graining of quantum correlations leads to classical correlations in the macroscopic limit. Such a principle, known as macroscopic locality, has been proved for correlations arising from independent and identically distributed (IID) entangled pairs. In this work we consider the generic (non-IID) scenario. We find that the Hilbert space structure of quantum theory can be preserved in the macroscopic limit. This leads directly to a Bell violation for coarse-grained collective measurements, thus breaking the principle of macroscopic locality.
